Hello, I've had my Model S for a little over a year now, and had a NEMA 14-50 outlet installed in my garage, and its been working wonderfully. We've decided to update the kitchen, and part of the plans require a dedicated circuit for a new electric oven/microwave combo (requiring NEMA 14-50 240V/40amp service), a new circuit for a wine fridge, and another circuit for some new lighting. Our main panel is Cutler Hammer and has 42 slots. Our house was built in 1993 and has 200 amp service coming from the electric company. Over the years we've added quite a few things (pool pump, two zone AC, etc) and now we only have 4 slots left. Fortunately when installing the NEMA 14-50 in the garage for the Tesla, I was anticipating that we might need a subpanel. The Tesla outlet is located pretty far away from the main panel, so I had the electrician run 4 separate cables (6 AWG each) in a conduit to a junction box in the basement near the garage. He told me that I could upgrade to a subpanel much easier later if he did this. The needs for the kitchen would require another 4 normal circuits (120v/15 amp) and 1 240v/40amp circuit for the oven/microwave combo. I anticipate the peak load for all of these to be no higher than 45 amps. We might be able to squeeze everything into the existing 4 slots of the main panel, but I was thinking instead of installing a sub-panel. If an electrician were to come and install a new subpanel, he would presumably take the existing 4 x 6AWG wires and use that. Then within the new sub-panel, 2 slots would need to be dedicated for the Tesla 14-50 outlet. My main question is this: considering the anticipated load with the new kitchen appliances, is it acceptable to have the Tesla 14-50 outlet wired off of the sub-panel instead of directly to the main panel? I guess I'm worried that the combination of the Tesla 1450 load plus the kitchen stuff might cause lots of tripped breakers. I've uploaded a wiring diagram and a few photos to help explain. Any advice would be appreciated.
